Barrier spray on foliage and fence lines knocks down adult mosquitoes fast, but larvicide in standing water is what actually breaks the breeding cycle. Mosquitoes can travel a few hundred feet from a breeding source, so a neighbor's uncovered rain barrel can still affect your Delafield yard even after your own property is treated.
We walk your Delafield yard for gutters, planters, and low spots holding water that spray alone would never address.


Every technician treating Delafield yards for mosquitoes carries state pesticide application licensing and liability coverage.
One-time treatments ahead of an outdoor event can usually be scheduled within a day or two.
Monthly treatment plans are quoted as one flat seasonal rate covering the full peak-season schedule.
Our equipment includes ULV fogging units for rapid knockdown before an outdoor event.
Bti-based larvicide targets mosquito larvae specifically without harming beneficial insects in the same water.
We treat the underside of leaves and dense foliage specifically, since that's where adult mosquitoes rest during the day.
A monthly schedule through peak season keeps mosquito pressure consistently low instead of spiking between one-time treatments.
One-time treatments are timed to peak just before your event for maximum knockdown when it matters.
We flag chronic water sources — clogged gutters, low spots, unused pots — that keep re-seeding the population between visits.
Yards near wooded or grassy areas often need a separate granular tick treatment along the perimeter where pets and kids play.

Our mobile units carry both barrier spray and larvicide product so no return trip is needed for mixed treatment.
We walk the property, flag every standing-water source, and quote a flat rate for one-time or monthly service.
Barrier spray and larvicide go down the same visit, with monthly plans scheduled automatically through peak season.
They found a clogged gutter section we never would have thought to check, which turned out to be the real breeding source.
Needed the yard treated fast before a backyard graduation party and the fogging treatment cleared it out just in time.
We're near a wooded lot and mosquitoes plus ticks were both a problem. Bundling both treatments into one visit was convenient and cost less than doing them separately.
The technician pointed out an old tire in the side yard holding water that we'd completely forgotten about — that alone made a noticeable difference.
